Menopause

Menopause marks the end of a woman's menstrual periods. A woman has officially gone through menopause when it has been one year since her last period.

In the months to years before menopause—a time called perimenopause—the production of hormones that regulate the menstrual cycle changes.

In the United States, the average age of menopause is 51. But there is a wide range: some women have their last period in their 40s, others in their late 50s.

Anything that damages the ovaries or stops estrogen production can cause menopause to occur earlier. These include:

  • smoking
  • chemotherapy or radiation therapy
  • surgery to remove the ovaries

Symptoms of menopause

Each woman’s experience of perimenopause and menopause is unique. Common symptoms of perimenopause and menopause include:

  • irregular periods
  • hot flashes and night sweats
  • vaginal dryness
  • disturbed sleep
  • urinary incontinence

Women are also more likely to develop depression for the first time or have it recur. Some women report trouble with memory and the ability to concentrate.

Easing menopause symptoms

There are effective ways to deal with some of the symptoms of menopause.

Irregular periods. Low-dose birth control pills are an option for nonsmokers. Use of progesterone-like hormones also can help control heavy, irregular bleeding.

Vaginal dryness. Over-the-counter vaginal moisturizers can relieve dryness.

Hot flashes. Many women can manage hot flashes with self-help approaches like beginning deep-breathing exercises at the beginning of a hot flash, wearing loose, comfortable clothing and dressing in layers, keeping the work place and home —especially the bedroom — cool.

Taking estrogen or other hormones can be safe and effective for short-term relief of symptoms like hot flashes and night sweats—provided it’s prescribed with a woman’s individual health in mind. Hormone therapy is also effective for preventing osteoporosis in women at high risk for breaking bones.

When sex gives more pain than pleasure

Millions of women experience pain before, during, or after sexual intercourse—a condition called dyspareunia. Many suffer in silence and don't seek the help they need, or they have trouble finding a clinician who can diagnose and treat the causes of their pain. That is unfortunate, because treatments are available for many of the problems that underlie this vexing condition. More »

Bioidentical hormones: Help or hype?

Bioidentical hormones are promoted as being safer than FDA-approved postmenopausal hormones, but their production is not regulated and their claims of effectiveness have not yet been substantiated by long-term clinical trials. there’s been growing interest in “bioidentical” hormones, which are promoted as safer and more effective than FDA-approved hormones. The interest is driven in no small part by claims made in entertainer Suzanne Somers’  book, Ageless: The Naked Truth About Bioidentical Hormones (and her appearance on the Oprah Winfrey Show).

Another drug prevents breast cancer in postmenopausal women

Exemestane (Aromasin), tamoxifen (Nolvadex, generic) and raloxifene (Evista) are three drugs used to prevent breast cancer in postmenopausal women who are at elevated risk for the disease. Exemestane appears to have less frightening side effects — hot flashes, joint pain, and loss of bone density. All three of these drugs target estrogen, which fuels the growth of most breast cancers, but exemestane belongs to a different class of drugs, called aromatase inhibitors, which work by blocking the body's production of estrogen. Previous studies have shown that aromatase inhibitors are more effective than tamoxifen in preventing breast cancer from recurring. This study, funded Pfizer, and conducted under the auspices of the National Cancer Institute's clinical trials unit, looked at whether exemestane could reduce the likelihood of a first occurrence of breast cancer.
